I've found that there is no problem when playing back by the camera itself. Even you zoom in the video, the quality of "\" lines is the same of the "/" lines, in the OLED screen.

The bug exists ONLY in software playback, all my tested softwares, including QuickTime, VLC, ffdshow.

So, it's possible a small program or filter software can fix the problem of the files recorded, before the firmware update is available."

Wayne Morellini · June 16th, 2006, 08:24 AM

That's curious, it might indicate that the screen gets uncompressed video (though the zoom is going to have to have at least 4 times the resolution to come up on the smallest pixel, 16 times before you can easily see it on the small screen).

I think the fault is recorded by the camera. What do you see when you playback from the camera to HD screen (or TV with 4-16 times zoom)?

Carlos Serrano · June 16th, 2006, 08:52 AM

I´ve just connected the camera to a HD projector throught component cable and the problem is still there.:-(

Bo Lorentzen · June 16th, 2006, 09:11 AM

Carlos,

Thank you for trying that, I was thinking the same thing yesterday.

Too bad, for one moment I was thinking that one could do straight playback and skip the problem... Oh Well. soo much for dreaming. (smile)

Processing software to get rid of it should still be possible.

I've just noticed something interesting about the AVCHD camera format (18Mb/s h264) is that there is no 30p or 25p 720p, it goes from 24p straight to 50/60p. I think it more likely now that those modes will have 18mb/s. Should give pocket cams with out the quality problems of the Sanyo. I wonder if anybody over at the AVC threads have noticed this:

I kind of agree with Manu, I don't see the jagged edges when watching videos in my HDTV, just a hint of blurriness in the edges (but I have to try very hard).

In the computer screen however, is very evident.

I use a 55" projection TV and for playback a Showcenter 200 network media player. My guess is that there is some kind of interlacing that is "fixing" part of the problem, probably because the output of the showcenter is 1080i.

Carlos Barbino · June 19th, 2006, 04:22 PM

Wayne, regarding the AVCHD standard: wouldn't 50/60P be better than 25/30P?

You can always throw out every other frame in post production to get a 25/30P product from the 50/60P stream, but the higher frame rate is there if you want smoother motion or to get a slow motion effect.

Wayne Morellini · June 20th, 2006, 11:37 AM

Yes, it is just likely that these modes might get the full 18mb/s. 24p might be reserved for more expensive cameras.

Also dividing the 18mb/s into 60/50fps, leads to lower performance then 30/25fps. I think it is a bit too much, but as 24fps is the main worry for quality, maybe it will be alright if that can work at 24fps. I still prefer the 50mb/s intra frame pro version though.

Chris Taylor · July 24th, 2006, 09:04 PM

So will the HD1A have corrected firmware ??

Roman Oulko · July 28th, 2006, 09:53 PM

After getting tired of all problems with my camera and frustration that I can’t return because it been more that 30 days and sending emails to Sanyo with no response. I have decided to go directly to Sanyo’s office in Chatsworth CA. Yesterday I went to them . I spoke with John I tried to explain and show him what problems I (we) have 1. Stabilization 2. Low light recording 3. Purple leaves instead of green and my dog purple in HD. He denied that problems exist with camera at all and they have not received any complains but he said that some cameras experiencing problem described here http://www.dvinfo.net/conf/showthrea...645#post495645 even though he saw purple by himself when he made a small video inside an office. I told him either fix those problems or take camera back. He said that he can’t fixed problems in my camera because there is nothing wrong with camera. He gave a phone number of Mr. Duarte I spoke with him today he said same thing there is no problem but I asked him to take look at my camera one more time and I will bring more footage he agreed . So, I will bring my camera with footage On Monday at Sanyo office and leave there and he will call me back with results. So if anyone has footage with problems give a file I try to transfer to my card and give it to him. oh yea and John told me that HD1A is almost same camera just more features
Thank you

Wayne Morellini · July 28th, 2006, 11:52 PM

Roman, there are many threads here with reports of various (many) bugs, purple dog sounds like another one, and many sample clips that you could download. But if anybody has better, please send to Roman. Unless they were designed in Mpeg4 that way, there is no way it is not a bug, and that goes for a lot of things.

It would be interesting to find out how many readers, including the hidden ones, have found bugs? Would be suggested for all readers to report everything to Sanyo.

Graham Jones · July 29th, 2006, 03:18 AM

Well done, Roman.

Rafael Rivera · July 29th, 2006, 12:33 PM

Roman, I have two movies you might want to use. They're not my best examples of a defective HD1 I returned to Amazon (great place to purchase gear from, though), as those never made it past the early editing stage. But I've got two that show a split screen difference in exposure and artifactual bars of alternating exposure levels. I can also attest to the purple artifact as well, still present in my replacement HD1. Email me to let me know if you'd like to download them, and I'll send you the links.

Lance Richman · July 30th, 2006, 01:44 AM

seems like a minor issue but it is a very visible defect in recordings of lower light levels. If they told me it had this problem I wouldn't have bought the camera. I took a quick vid just now, the problem is noticible. IMO the room is well lit enough to take good video. Other times it is much worse. Here is the link

http://www.lanceandrachel.com/SANY0035.MP4

There is a definite vertical line about the middle of the screen, with the entire left side looking different from the right. You can minimize the effect some by messing with some of the settings however slight changes in light levels or background can make it stand out prominantly. I had hoped that it was a viewfinder issue but it shows up in the recorded video. It is not a memory card compatibility issue, the camera shows this problem with no card at all.

If you could talk to them and get some information from them about this I and others with this problem would be most grateful. Good luck and thanks.

Roman Oulko · July 30th, 2006, 07:26 PM

Hi Lance i just downloaded your file and transferred to my my camera.
thank you for footage
