So I checked the supported file formats in PD20 itself, and it does include 3GPP2 as one of them. However, this is what MediaInfo says about the two video clips that I have:
MPEG-4 (3GPP Media Release 5), 325 kiB, 30 sec 427 ms
1 video stream: H.263
1 audio stream: AMR
First video stream: 79.9 kb/s, 176*144 (4.3) at 10,000 FPS, H.263
It looks to me as if PD20 cannot use these files because they are only 3GPP / H.263 rather than 3GPP2 / H.264. Is that correct? (If so, very disappointing because these are two of her 'first words' video clips.)
Again looking at my PD20 user guide, it only mentions MPEG4 as MPEG-4 AVC (H.264). Does that mean that PD20 does not support H.263 video files at all?
It seems illogical that there wouldn't be a way to upconvert H.263 to H.264, especially as there must be scads of H.263 video clips around from "back in the day", lol
Thanks for any advice!
