First of all, thank you Topaz Labs for this revolutionary product and having listening to the requests of having it not only a cloud pay for use product but also a local desktop program.
I tried the Beta app since november and was already conviced so as soon as the final version was released I immediatly purchased it before even installing it and launch any trial .
First feedbacks : Like I was for the beta I was surprised of the output video codec. It’s the 15+ years old mpeg-4 part 2 codec aka h263 and without any choice of the output bitrate. Is there a specific reason for that choice ?
So for now I only use still images outputs for the best quality output for a use with lossless codecs or pro codecs like Cineform, ProRes on post processing programs using images sequences input. Yes files are incredibly huge but that’s why 6-8-10+ TB hard disk drives are made for after all. And you will have a high quality master file for your post processing, editing etc.
My first request would be the choice of the output codec and settings. The app relies on ffmpeg after all so this should be easilly done at least using a command line like the beta version had.
Also converting SD footage to HD is tricky because they don’t use the same color space standards.
SD uses Rec601 specifications and HD Rec709, so by using the direct video mp4 output you will end up with an HD video encoded with rec 601 spec and it’s wrong because players and even edit softwares will decode it with the rec709 matrix and the colors will not be correct. The output must be flagged as bt 709 using internal YUV 601 to YUV 709 pixel format conversion before encoding.
Other requests :
- maybe a jump to a specific frame of the video would be useful and more precise and faster than the slider
- a command line option like in the beta
- more than 30 frames preview when we try to figure wich model is the most suitable to use
