Yes. Upload any JPG or PNG and PDF.to centers it on a solid background for the whole M4V. This is how you give a AMR track a branded video thumbnail.
M4V 是否将标题和艺术家标签 与我的AMR 保持了?
+
Where the M4V container supports metadata, title and artist tags from the AMR are carried over. The cover artwork embedded in the AMR is also used automatically if you do not supply your own.
我可以把很多 AMR 文件转换到 M4V 吗?
+
Yes. Drop a folder of AMR files and each becomes its own M4V video; all of them are zipped for a single download.
Is the AMR to M4V conversion free?
+
Yes, within the free size limit. PRO unlocks much larger AMR uploads, longer durations, and parallel jobs.
How long can the AMR be?
+
长相相册和多小时 AMR 录音转换为罚款。 因为图片是静态的, 甚至长为M4V 的大小也比长为相同的录像片子小。
Will the M4V play on YouTube, Instagram, and TikTok?
+
是 PDF.to 编码 M4V, 并有广泛支持的编码和像素格式, 因此由此产生的视频会被清晰地上传到拒绝光线 AMR 音频的主要平台上。
