Our of our readers Chinito Pinoy has shared a pretty remarkable video with us that we would like to share. It is upscaling of sub HD resolution high-speed video at 240p, 480p and 960p from the Sony RX10 IV at 480 and 960fps and the A7S Mark III at 240fps from Sub HD to 4k UHD.

Rife-App Creates Higher frame Rates 25x Faster!
A few months back we took a look at Dain app, and how it was able to use AI and machine learning to create in between frames from almost any source footage and create something that looked and felt like real footage taken with higher fps cameras. The algorithm was so revolutionary that it took the world by storm, making older software that used re-timing from Adobe and others look antiquated and underpowered. The Dain-App was great and it was a pay what you want App but had an Achilles heel. The software required a powerful Nvidia GPU with as much VRAM as you could muster to be able to convert footage and re-time it.
The new Rife-App which is the direct successor of Dain App by the creator GRisk is up to 25x faster than the original, improves the algorithm, and by many examples betters it by creating more seamless transitions. The flow of frames is frankly jaw-droppingly beautiful, especially on low frame rate animation. We estimate that Animation studios in 2D will eat this app up immediately, and even 3D animation studios could reduce their render times by calculating fewer frames and using Rife-App to increase them to 24p, 30p or 60p from a lower source like 20fps or 12fps.
Multiply Your Video Frame Rate with Dain-App !
We got over 20 messages with essentially the same video sample in our inbox this week. They all touted the new interpolation from the DAIN experimental App or (Depth Aware Video Interpolation App) which now analyses footage with a Neural network AI algorithm that crunches motion vectors and even what seemed impossible before “Object Occlusion” to generate higher frame rates from lower fps sources. The technology is pretty fascinating and should be further improved by more training and samples over the coming years.
For stop motion animators, this is a complete game-changer as now you could animate with as little as 8fps and then interpolate to 30fps or 60fps with very little in the way of tearing and artifacting as long as the footage is well lit and objects clearly defined. To make matters more interesting, it also analyses footage with shallow depth of field yielding impressive results.
Multiply Your Video Frame Rate with Interpolation or the “I” Word for Slow Motion Enthusiasts:
We visited the Interpolation topic in the past on our Fake Slow Motion article and concluded that then, the quality of interpolation while good was far from usable and you really could not compromise real high fps footage from interpolated versions except in very simple cases.
Now with DAIN technology, we have no choice but to re-visit the cases and analyze what it is capable of. We looked at a few dozen examples and it is clear the technology has progressed forward so much that now stop motion animation, 2D Cell-based cartoon animation, and even 3D animated sequences rendered at 30p can easily be turned in higher fps increments yielding impressive and in some cases miraculous results.
We would like you to first watch the video below to understand what a depth map is and how the software in DAIN can create frames from nothing that look just like real ones. A depth map will generate an approximated view of the world in a Lidar-Like vision representation to figure out to the best of the AI estimation where objects are in a scene according to their location close or far to the camera.
Depth-Aware Video Frame Interpolation by Wenbo Bao:
Even at 48fps from 12fps source, it is clear the technology in DAIN can yield impressive results even with heavy organic detail in the background including foliage. The software does an admirable job of estimating the relative position of objects in the video scenes.

Canon EOS R5 Makes it Expensive to record 120fps 4k Video!
Canon has now released the final specs and estimated release dates for the EOS R5 and R6 cameras. There is a lot of good advancement in features especially in video mode as what many believe is an afront to Sony and Panasonic who dominate video recording on ILCs. The R5 can record 24fps and 30fps 8k video or 8192 x 4320 pixels in RAW quality which is a staggering 1TB of storage or 2600 Mbits/s for only 51 minutes of recording time. That means that every hour you will eat up through a full TB of your RAID backup storage. We see this mode being transcoded to an intermediate format like Blackmagic RAW or BRAW or Apple ProRes as soon as possible.
There is more bad news, on the 120fps 4k front there is no other option of recording but All-I which saves every frame independently in 10-bit 4:2:2 which is good for excellent quality but at the cost of 1,880 Mbits/s which is 224MB/sec or 13,447MB / minute of recording time. Better get a ton of memory cards and hard drives ready!

You read that right 120fps 4k video on the EOS R5 is only possible at the 1,880Mbits/sec data rate even in H.264 mode. Also interesting to know is the lack of 120fps Full HD 1080p or higher fps modes which are common on cameras from Panasonic or Sony.
Yes, the R5 gets overheated after recording video on the following modes and times:
- 8k RAW 30p/24p – 20 Minutes rec time
- 8k NON-RAW 30p/24p – 20 Minutes rec time
- 4k 120fps – 15 Minutes rec time
- 4k 60p – 35Min Rec Time No Crop
- 4k 60p – Crop Mode 5.1k Oversampling – 25 Min Rec Time
- 4k High-Quality 30p- 8.2k Oversampling- 30 Min Rec Time
- 4k 30p – No Overheating Limit
We do not find any of these limits to be unbearable if you shoot clips of a few minutes but for event shooters, this is not the camera for you for many reasons, chief among the rec time limit, and secondly, the massive recording space needed. For slow motion, the limit of 4k 120fps at 15 minutes is probably more than you will ever need so that is not a problem. See the video below:
Canon EOS R5 the TRUTH about OVERHEATING!: Armando Ferreira
It costs what :-0?
Yes, the EOS R5 costs a staggering $3,899.00 US Body only and expected to ship at the end of July on the 31st. The camera it stems from the venerable 5D Mark IV DSLR went on sale in September 2016 with a retail price of $3,499 (Now about $2,000USD), so the new R5 is now $400 USD more expensive at launch plus the new lenses are really expensive plus also needed to get the most out of this camera’s 45MP sensor and be able to get the 8 stop Sensor IBIS Stabilization with lens+body. A good R5 kit will probably cost you around $10k for a three-lens setup with body and memory cards. Having the latest and greatest from Canon or any other big brand will cost you, and this is a prime example of it.
4k 120fps Mode samples?
Gladly we were able to find 4k 120fps video samples from the R5 and they look very good along with full AF which is an excellent feature to have in slow motion recording see below:

Canon EOS R5 gets serious about high frame rates!
We were very skeptical earlier in the year when the R5 specs were just a rumor. Canon has not really been delivering powerful video features out of their Cinema line and we expected this new camera to be a crippled continuation of the trend. We were not only wrong but now know that Canon is banking the future of the EOS line on cameras like the R5 with features that really put it in a class all by itself.
The original video darling was the EOS 5D Mark II which made it possible to use the EOS line of lenses with a video mode that delivered good enough quality for the web and some careful productions. The camera had issues like severe rolling shutter and a tendency to moire and alias so bad that many shots were really ruined. However, the excellent Canon color quality and lens choices made it so popular that it really forced companies to change the video options forever. Now Canon intends to do as big a splash with the introduction of 8k video internally on the new camera.
Canon EOS R5 Released Specs:
- 8K RAW internal video recording up to 29.97 fps
- 8K internal video recording up to 29.97 fps in 4:2:2 10-bit Canon Log (H.265)/4:2:2 10-bit HDR PQ (H.265).
- 4K internal video recording up to 119.88 fps in 4:2:2 10-bit Canon Log (H.265)/4:2:2 10-bit HDR PQ (H.265). 4K external recording is also available up to 59.94 fps.
- No crop 8K and 4K video capture using the full-width of the sensor.*
- Dual Pixel CMOS AF available in all 8K and 4K recording modes.
- Canon Log available in 8K and 4K internal recording modes.
- A Canon first, the EOS R5 will feature 5-axis In-Body Image Stabilization, which works in conjunction with Optical IS equipped with many of the RF and EF lenses.
- Dual-card slots: 1x CFexpress and 1x SD UHS-II.
Yes, Canon grows up the video mode…
You read that right we have 8k 30p and 24p using the full-frame sensor width with no big crop “excellent for punch-in interviews” and also up to 120fps at 4k 10 bit 4:2:2 color which beats Panasonic’s 60fps limit on that mode. The R5 is a beast of a camera that is set to deliver on every front.
We love that it has the dual pixel AF on all modes with the latest intelligent AF modes including eye AF for people and animals. This is probably the most advanced and useful video AF that produces excellent results without much stutter. The nightmare of focus pullers as their job just got harder.
What about 1080p HD frame rates?
Sadly Canon has not released any information regarding the HD modes on the camera but we have an idea of what that may be. Since 4k will have 120fps in NTSC and 100fps in PAL, we expect at least to have 240fps in Full HD 1080p with probably no 720p modes due to redundancy.
We may see a sensor crop on full HD to allow such frame rates at 120fps and 240fps but we do not expect a crop on 24p, 25p, 30p and 50/60p which should be full frame. Crops on higher frame rates are common as many sensors cannot scan that fast for the entire sensor area. We may even see some crop at 4k 120p which is not specified in the released information. It will be interesting what Canon shows when the full specs are out including the price which we may see reach a range of $3,299 to $3,999 USD as an educated guess.
We cannot be left unimpressed by the EOS R5, Canon has finally awakened from their video slumber in the midrange lines and is delivering a hard punch to the competition.
Sony and Panasonic will not stay put and allow Canon to take the praise without some hard releases. We expect Panasonic to have a new S1 camera that may shoot 8k as a GH camera in a GH6 or similar that should be able to shoot 8k also. As for frame rates in HD resolution, we may start to see higher than 240fps on competitor cameras. Panasonic, after all, has had 240p on the GH5s and 180p on the S1 series with good results.
Sony may also release a new sensor with a higher memory buffer allowing super slow motion like their RX line of cameras. Could we see the first Alpha camera with 480p or 1000p in reduced time recording modes? That will be a nice sight to see.
We commend Canon for pushing the industry forward with a Camera that may be just as important as the 5D Mark II was over 10 years ago, now as an 8k capable powerhouse with incredible quality and features like sensor/Lens Hybrid Full-frame IBIS stabilization and full-time Dual Pixel AF with machine learning.
We just need to get that Virus beat so we can go out and test these awesome cameras. More information on the R5 as it becomes available -HSC

Z Cam E2 Starts Shipping To Customers!
The Z Cam E2 has finally started shipping and is now available for direct order at their site. The camera caught our attention for its low price of just $1999 and the high frame rate features of 240fps 1080p and 120fps 4k. It seems to be using the same 4/3 sensor as the great Panasonic GH5s but with extended features.
The camera company ZCam has also released some samples in a variety of scenarios so you can see what the camera is capable of. At first inspection, it is clear this camera is a clear step up from the Z Cam E1 which had some image quality issues. The E2 seems to go out of the box ready to produce class-leading imagery and offer some very nice high frame rate action. There are also some rumored comments that suggest the team is testing 300fps at 720p as an added bonus for future software.
Z Cam E2 Main Features:
- 4K @120fps, 10-bit color
- 4/3″ Dual Native ISO sensor
- 13 stops dynamic range

Z-Cam E2 Testing at Afton by EatsTooMuchJam:
It is clear the Z Cam E2 camera is capable of some very high-quality video output and could be easily used for cinema productions as a crash camera with remote access built in. However, the camera’s lack of screen and irregular cuboid shape may put off some buyers and it may not be for everyone. Add the fact that it shoots 4k 120fps and 240fps at 1080p makes it a desirable higher frame rate solution. For under 2k this is one camera you may be able to afford as a production assist with also the quality needed for drone imagery without being too bulky. –HSC
