If you have home movies saved with your other videos (i.e. in the native videos app, NOT in the camera roll), you may be disappointed as this app can only access videos in the camera roll. I contacted the developer twice to find out how I could access these videos through this app, but both e-mails went unanswered. Another third party app I have (VideoPix: Video Frame Capture...) accesses the videos there just fine, so I know it IS possible to access those videos. Since this is a video to photo grabber app, it seems basic that it should be able to access these videos, but it cant. This should have been disclaimed before purchase. For videos that are in the camera roll, this app does a pretty nice job of taking pix, however: (1) there is no way to preview in full screen so it can be hard to see what clips are best to save (the small size makes it difficult to assess the clarity of any given frame), and (2) there is no easy way to jump to exact locations. The scrolling feature is good and the quantity of images displayed is good, but it can be very difficult to go through them all (hundreds/thousands of images) with the present options. If there was a way to quickly jump forward 5/10/25/30/50/etc. frames this would help (remember there are something like 30 frames per second so even the shortest videos can have quite a few frames to go through). The slider on the bottom is much better than nothing, but it would be helpful if there was a more exacting /easier method to go through so many clips. Also, it is annoying after EVERY save to have to click ok or rate this app. It seems kind of inefficient to have to 1-tap to select, 2-tap to save, 3-tap to say okay, 4-tap to go back. I think all this could be accomplished with 1 or 2 clicks instead of 4. It adds up over time, especially if you are saving a lot of images. BTW, I would have rated this app higher if I could access videos and if the support e-mails had not gone unanswered. The app itself is probably worth a good 4+ stars if you dont need to access videos outside the camera roll and dont care about customer support.
