AMV video format

Post by Strassboom » Thu Feb 09, 2017 2:28 pm

Hey there,

Quick question about the format of our videos. Is it alright if the output is 30 or 60 frames? And will the audio/video synch or audio quality be affected when we convert the video to your format with the tool provided on your AMV programming page?

Thanks in advance!

Our playback system can handle a wide variety of frame rates; the frame rates in the suggested technical specs are just standard ones that we've found work very well.

The tool will not change the resolution or frame rate of the video file you provide to it. However, if your video is already small enough to upload through the form (<1000 MB), you don't need to reencode it with the tool, especially if you've already encoded it with a lossy compression method (which will reduce the video quality).

Videoscaling

Post by Strassboom » Wed Feb 15, 2017 12:37 pm

If I am using footage from an older tv series and a film, and they have different aspect ratios i.e. 4:3 and 16:9, am I allowed to zoom in on one to compensate so long as theirs no noticeable loss in quality, or do all clips have to be at their normal aspect ratio? I don't wanna have to worry about black bars. Also would be allowed to do this to hide watermarks? Thanks in advance!

The video quality rules are concerned with the final product you produce. Nobody cares how you get there.

That said, creating a (good, properly filtered, correct AR)* upscale of 4:3 footage to your target width during your footage prep step and panning it as needed is the generally accepted way to combine 4:3 and 16:9 sources.



*: A simple resize of SD, 4:3 footage to HD resolutions by itself is not going to look good.
