Problems with MOV to WMV conversion.

posted in Video Codecs

I am having difficulties converting a couple of videos I filmed with a digital camera into WMV. They are .MOV but instead of having AVC format (like some other videos I filmed with a different camera that I successfully converted)they are M-JPEG.
The program I am using is eRightSoft’s SUPER (and I tried using a number of other conversion programs, none of which worked except VideoPad Video Editor which is not satisfactory because of the low quality conversion

Is there some kind of codec I must download for SUPER or any other program that can handle this?
When it comes to these things I’m as smart as a 5year old, so I have no idea where to start and why its such a big deal that the MOV is in M-JPEG format.
Here’s a screenshot of specs of the video that does not go through the conversion:

Here’s another MOV that worked with conversion which I filmed with another camera:

I show you this so you can see the specs in the event that EVERYTHING I HAVE CLAIMED IS IRRELEVANT.
I just need a way out. Any suggestions? reply

No worries, most of what you posted is relevant.

I’m unfamiliar with Super, however my suggestion would be to try using MP4CAM2AVI (freeware) to change the MOV Photo JPEG file (P1020248.MOV) to AVI Motion JPEG. The change of container (from MOV to AVI) would be lossless if you pick the right settings (action: batch convert many->many, audio format: source audio (no recompression)). The video and audio streams would be taken from the MOV and put unmodified into an AVI file (which hopefully Super should handle better).

If you have any curiosity when encoding to WMV files, I would suggest trying Microsoft Expression Encoder 3. It’s freeware, and has much more options and control over settings like quality. The only downside is if you’re on XP or Vista, it requires the .net framework 3.5 (which is rather big and clunky; but you may already have it, then it’s no biggie; .net 3.5 is already included in Windows 7).
One big plus is Microsoft Expression Encoder can read MOV files if you have Windows 7 or you have QuickTime installed.

Also correcting a small inaccuracy: P1020248.MOV has fourcc 'jpeg', therefore the codec is “Photo JPEG”, not “Motion JPEG”.
In MOV files, you can have Photo JPEG (fourcc 'jpeg'), Motion JPEG A ('mjpa'), and Motion JPEG B ('mjpb'). Photo JPEG is for progressive images, whereas the Motion JPEGs can also handle interlaced contents.
In AVI files, you have Motion JPEG (no A nor B) with fourcc MJPG.
AVI Motion JPEG and MOV Photo JPEG are pretty much the same except for their name and fourcc (the video stream I mean - the file container is obviously different since one is AVI and the other is MOV). This resemblance may be why Super refers to MOV Photo JPEG as “Motion JPEG”.
If you’re unsure, check in QuickTime (click Window, show Movie Inspector).

Just an aside: I recognized the digital camera prefixes. The MVI is Canon and indeed H.264 (avc1) (fine videos from that line of cameras IMHO), and the P102 is either Olympus or Panasonic. (If it’s Olympus, be sure to set the date on the camera, or you’ll get P101’s and wrong dates. If you set it right, and you shoot a movie tomorrow, you should get P603. For Olympus, first digit is month (1=Jan, 2=Feb, ... A=Oct, ... C=Dec), next two are day. Useful for keeping track of date you shot a picture/movie.) reply


Yep, its Canon and yep, its Panasonic. Thanks a lot for your help and time, I’ll try what you suggested! reply
