Thank you for the original Yupiteru DRY-FH31 sample video file. First I was curious about your editing problems. I don't have Premiere, but the old free VirtualDub which is great for simple edit the avis.
The problem with the AVI created by this camera I found on another Novatek chipset camera and is about not standard AVI files. If you want just to cut and direct stream copy (no reencoding) some part of the video, the image will be black.
I understood this is because the information about the video are contained only in the first frame of the recording video file.
So if you want to just simple cut or join this type of avi you always must to reencode it (which will affect the image quality a little even if using good encoding options).
For me the simple solution if I want just to have few parts from the recording which is at the original quality is to use the free and great MKVMergeGUI to create a MKV file.
For example here I want just the video from second 25 to second 45 (but no precise frame cutting, just seconds).
This is the result obtained in few seconds of work from me and is playable. If I want to do the same thing using Direct Stream Copy of VirtualDubMod, the video image is black or containing big error macroblocks.
Yupteru should offer MP4 or MOV container instead of AVI and increase the bitrate to 7500kbs. Actual 6500kbps is OK but not enough.
enjoy,
Mtz
