hello,

I just bought an Archos 43 Vision, and I was very excited to load up my music on my 16GB MicroSD card, and that I had found a player at a reasonable price with this capability. I loaded up my music to the MicroSD (and some to the actual player), popped it in the SD slot, and then left home with it, planning to get great use out of my brand new player. When I play music on my SD card, it sounds AWESOME... for a short time. About 2:00-2:45 into EVERY song that is stored on my MicroSD card, the audio quality plummets from excellent down to the quality of an old and used cassette tape. When I move those files from the SD card to the player, the audio quality is perfect. I am highly disappointed in this, considering I am planning to put a minimum total of approx. 22-24GB of music on my player, once the SD is factored in.

When I play music stored on the actual player, I can play that all night long (literally) and the audio quality will never decrease... at all. I have not had a chance to test to see if the SD audio quality eventually goes back up, but I can do that, and I will post the results here.

Second, I downloaded some episodes of a TV show from zshare.net (they are all 24:04 in length), and the player is only able to play the first 4-5 seconds of the video. All of these videos are in .avi format, and I experience the same problem whether the files are on the SD card or on the internal flash memory. However, I am able to play other .avi files, so the problem is likely to do with either the original source of the file (before it got uploaded to zshare), or it is a problem with files from zshare.net specifically. If you like, I can post the URLs to the files, if you want to download them and try something for yourself to see if they work for you.

Another minor video problem I have is with a concert DVD that I downloaded via torrent in the form of two .avi files. Playing the file works just fine, the only problem is the video lags behind the audio at various times. It is not the video a/v synchronization within the file - in places it was lagging the first time I watched it, the second time around it lagged in different spots. What would cause this?

Also, is there any limit at all to how much SD memory this device can handle? for example, if I wanted to put a 64GB MicroSD card in and load it up with all kinds of memory, would that work?

Thanks! I am looking forward to hearing back from a moderator/admin, but if any fellow users have any suggestions, I will try those as well.

Despite the fact that the 43 Vision`s main selling point is the fact that people only need to click and drag files to the player without reencoding or converting, I found that it is preferable to do so in order to get the most out of the player. In addition, you`ll maximize memory capacity.

For videos, I reencode my avis so that resolution is 480 X 272. I use a frame rate of 24 kbps and encode to XVID.

For music mp3s, I try not to exceed 192 kbps. Yes, I have one or two that are 320 kbps, but sometimes when I play those, I have problems.

The ideal profiles for AVIS, mp3s, etc. should really be listed in the manual or on the box. I think the specs listed on the box may have errors.

so, you suggest I download a video encoding program and try to re-encode them so that resolution is 480 X 272, use a frame rate of 24 kbps and encode to XVID?

Yes. You need to keep in mind that the Archos 43 Vision is a rebranded chinese PMP that came out a few years ago. Therefore, the tech is older, and you can't expect this player to play hi def videos or music files properly without choking. The files will play herky-jerky and they may be some audio sync problems.

Personally, I use Kigo Video Converter to reconvert my videos and music files.

Reencoding videos to the specs I gave you (480 X 272 screen, 768 kbps, 24 frames per second and XVID Codec. I also forgot to include that the audio portion of the video should be encoded mp3 and 128kbps and 44100khz), should give the maximum screen quality, while optimizing your memory capacity. However, if you try to reencode 3 hours plus movies like Avatar Extended edition, then you will have to lower screen resolution and sampling frequency, because the Archos will not be able to process files greater than 1 gig in its entirety.

I had to use trial and error and reinterpret some of the specs from my archos box. I think that there were some errors on the box, because they didn't match the info from the archos website. If anyone has any other ideas, please email me.

Hope this helps,
Marcel

Thank you for providing the specs and program that works for you.

I was able to get the videos to play for a longer period of time on my player, however, the program for some reason takes a 24:04 long video, and will only convert it into a 3:00 long video. I think I have a trial version. I will let you know how this works out when i am able to find a crack/keygen for this program. Thanks!

I can't speak for the windows version. I am using the Mac OS X version. However, it's still the trial version. Nevertheless, it pretty much has complete functionality without limitations. No watermarks, time limits, etc. Thus, the shareware is pretty much freeware. I don't understand why your 24 minute video wounded up only 3 minutes. If you need another program, try googling.

All I have to do is click and drag the file, choose my ideal profiles and press encode.

So yeah, I ended up using the free version of AVS Video Converter... The watermark is kinda annoying, but i'm willing to tolerate it for the videos i watch on it... havent had the chance to try it with any movies to see how the player reacts to that, but so far it's been acceptable.

Aside from Kigo Video Converter, another free encoder I use is FFmpeg. Again, this is the Mac OS X version, so I don`t know how different it is from the Windows version. If you decide to try it, let me know for future reference.
