I tried a free online SWF video convert today to test it on a project I’m working on for a client. I have some small .swf files that need to be converted to a video format in MP4 or AVI. After following the simple instructions multiple times, I continue to get the message “There was an error converting your file!” or 0 bytes output due to many possible reasons including wrong file type, corrupted file, wrong file extension. I tried converting different SWF files from multiple sources and had the same problems with all of them.

Troubleshoot-Cannot Sync MP4 to iPhone
The conversion to Mp4 goes fast and the output MP4 files play perfectly on iTunes, IINA and QuickTime player on macOS and MPC-HC on Windows. However, when I go to sync the file to my iPhone 7 I got the below error message that reads:
“final.mp4 was not copied because it cannot be played on this iPhone“
I was really frustrated to get this error message since the output is playing flawlessly and I am wondering around how to troubleshoot. There is my idea:
I previously set the resolution to 800*600 SVGA as I thought it would offer better MP4 files with better audio quality. I was wrong. I go and check on iPhone specifications and found the below spec for all iPhones, iPad, and iPods. You will notice in bold Apple only supports video with fewer pixels than 640×480 if the codec is MPEG4. However, Wondershare SWF to Video Converter only support MPEG4 for MP4 and MOV, we will then have to set the resolution to 640×480.
Video formats supported: H.264 video up to 1080p, 60 frames per second, High Profile level 4.2 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format.
- Set the resolution to iPhone. There is no such problem.
- iPhone is also able to play AVI files if the codec is MJPEG with less than 35 Mbps, 1280 by 720 pixels, 30 frames per second. You are able to do so with this SWF converter. Make sure you choose the codec MJPEG Compressor in Step 2 for video settings.
